Abstract

The corn harvester is composed of cutting and ear-picking unit for pulling out corn plants, cutting them for removing roots, and separating ear from stalk, breaking and separating mechanism for separating corn grains, and stalk-cutting unit for cutting stalk into bits and spreading the bits on field, and features simple structure, low broken grain ratio and easy separation of corn grains.

Description

Corn picker

The invention belongs to agricultural harvesting machine, be applicable to harvesting corn.

At present, China produces reaping corn machinery kind seldom, the corn combine of producing with Jiamusi Combine Harvester Factory serves as better, its primary structure is by the ceding of Taiwan, and conveying worm morcels machine and separating mechanism is formed, and it at first cuts down corn when work, deliver to cracker by conveying worm, corn straw and fringe are all pulverized, and then deliver to separating mechanism the corn seed is separated pack, return crop stocks to the field.Because it is that corn straw and fringe are pulverized simultaneously, cause waste so the corn seed easily is broken, moreover the corn straw of pulverizing and corn seed proportion approaches to and makes that separating mechanism is very difficult all to be separated the corn seed, further cause waste.

The objective of the invention is to design a kind of fringe, bar of making and pulverize the raising utilization percent separately, the corn picker that cuts the waste.

The present invention is achieved in that it is by cutting off spike-pulling mechanism, pulverizing separating mechanism and chipping field-returning machine structure is formed, the front upper part that wherein cuts off spike-pulling mechanism is fixed with thumb wheel, the bottom is fixed with guiding and dials and the ceding of Taiwan, guide plate tilts, its upper end is fixed two and is compressed conveying axis, wherein one outer every group has 2-5 semicircle reeds, and spring is given birth to the outer cover that also has, and reed is all and fixedlys connected with axle, cover; Dial cob for two and be fixed on the upper back that cuts off spike-pulling mechanism, the gap that this diaxon forms is consistent with the direction and the guide plate incline direction in the gap that compresses conveying axis formation, dials cob and compress all to have on the conveying axis external cylindrical surface to increase the raised or sunken of frictional force; The helical feed flood dragon is combined in the bottom of dialling cob admittedly, its bottom is fixed with conveyer belt, the outlet below of conveyer belt is a funnel of pulverizing separating mechanism, be fixed with two extrusion axises in the funnel, fixedly connected the pulverizing chamber that crushing shaft is arranged of its outlet, the outlet below of pulverizing chamber is separation chamber and the ajutage that is fixed with bolter, and the pipe lower end is corn seed and miscellaneous object outlet; Chipping field-returning machine structure is abutted against by gathering sill and group cob top.

The present invention compared with prior art because fringe, bar pulverize separately, so it is low to have a corn breakage rate, wastes little characteristics.

Be elaborated below in conjunction with accompanying drawing

Fig. 1 is a vertical view of the present utility model

Fig. 2 is an A-A cutaway view of the present utility model

Fig. 3 is a B-B cutaway view of the present utility model

The present invention is by cutting off spike-pulling mechanism 3, pulverize separating mechanism 5 and chipping and return mechanism's 4 compositions, the front upper place that wherein cuts off spike-pulling mechanism support 20 is fixed with the large dial wheel 19 and the small driving wheel 13 that can rotate, be fixed with the guide plate 21 of inclination in the front lower place of

support

20,22 and the ceding of Taiwan 23, guide plate 21, fix on two on 22 the end support 20, under compress

conveying axis

13,17, compressing wherein in the conveying axis 17 is a little axle 16, outside it, every group is fixed with 2-5 semicircle spring leafs 14, outside the spring leaf 14, axial restraint has 3-15 sleeves 15, move reed 14 and sleeve 15 of little axle 16 rotating bands rotates, because the effect of spring leaf 14 makes, under compress conveying axis 13, the crack can be adjusted automatically between 17, dial cob 10 for two, 11 are fixed on support 20 backs goes up the angle, this

diaxon

10,11 gaps that form, on, under compress

conveying axis

13,17 gap direction and guide plate 21,22 incline direction unanimities, these four axle external cylindrical surfaces all have the raised or sunken of increase frictional force, the helical feed flood dragon is fixed on 12 and dials cob 10, below 11, be fixed with conveyer belt 9 below it, conveyer belt 9 go out the funnel 24 that 8 belows are separating mechanisms 5, be fixed with two cylinders in the funnel 24 and wear raised or

sunken extrusion axis

25,26, fixedly connected the pulverizing chamber 27 that crushing shaft 35 is arranged of its outlet, being separation chamber 32 and the ajutage 30 that is fixed with bolter 31 below the outlet 33 of pulverizing chamber 27, is the outlet 29 of corn seed and foreign material bottom, 28.Chipping field-returning machine structure 4 is abutted against by gathering sill 2 and

group cob

10,11 tops.The power that cuts off spike-pulling mechanism 3, pulverizing separating mechanism 6 and chipping field-returning machine structure is all provided by belt or chain 7,6,1 by tractor.

During use this grain header is fixed on the tractor driving rod, puts belt or chain and adjust the high and low position of the ceding of Taiwan 23 and can begin operation.Large dial wheel 19 clockwise rotates and moves ahead, corn bending is backward stirred corn straw through small driving wheel 18 again and is entered upper and lower in relative rotation compressing in

conveying axis

13,17 gaps, compacted corn is cut off in the ceding of Taiwan subsequently 23, then send into and

dial cob

10,11 gaps in relative rotation, corn straw is crushed and carries to the back upper place, falls in the helical feed flood dragon 12 under dialling because the corncob diameter is big.The corn straw that is crushed is sent into mincing and returning to the field in the chipping field-returning machine structure 4 by gathering sill 2.Corncob is delivered to conveyer belt 9 by helical feed flood dragon 12, enter at last in the funnel 24 of pulverizing separating mechanism 5, through

extrusion axis

25,26 extruding, purpose is for corncob is flattened, cracker is easily pulverized, corncob enters pulverizing chamber 27 and pulverizes, enter separation chamber 32 from its outlet then, because the rotation of bolter 31 and the effect of the gases at high pressure that ajutage 30 is sent to make the corn seed separate with foreign material, the corn seed enters corn seed outlet 29 by the hole of bolter 31, and foreign material go out 28 by wind to foreign material and go back the field.So periodic duty, corn is promptly finished by harvesting.
